If you have packaged sources in your jar, you can extract them with any file extractor (like 7zip ) from the src folder inside the jar file. 如果您的jar中打包了源，则可以使用任何文件提取器（例如7zip ）从jar文件中的src文件夹中提取它们。

Otherwise you can use a Java Decompiler, this one has a GUI version too. 否则，您可以使用Java Decompiler，它也具有GUI版本。 The second method will not recover your comments/javadoc comments. 第二种方法将不会恢复您的注释/ javadoc注释。

Another method would be to use a disk recovery software, but that will only work if you didn't "securely erase" the files on your partition, as the files are still in the disk, just not indexed, and the recovery rate of this method is very low. 另一种方法是使用磁盘恢复软件，但这仅在您没有“安全擦除”分区上的文件的情况下才有效，因为这些文件仍在磁盘中，只是没有索引，因此恢复率很高。方法很低。 You can check testdisk and photorec for this. 您可以检查testdisk和photorec这一点。
